- Feb 25, 2008Carrageen:
I have tried to find suppliers of carragheen seaweed, but without
However, I ended up at a company providing different additives to the
food industry - among other things a lot of "thickeners".
We ended up that he sent me samples of a one type carragheenan powder
and one type CMC.
The first one consists of mainly ioata-carragheen - which is the type
that should not form a jelly - but give a viscous mixture, depending
on the concentration powder/water.
As I understood, in the food industry, there's a lot of
different "carragheenans" and they all are made of different
combinations of the 3 base types.
The second sample (CMC) seems to make similar properties when mixed
with water - but one need a lot less powder per unit water.
The one I tried gives a viscosity similar to thick cream at 1 flat
teaspoon per liter water. You have to mix in a high speed blender to
avoid lumps - and it seems ready for use after 1 hour "resting".
There is a lot of different types of this material - and CMC also
have a lot of applications. The rheology and lubrication properties
makes it suitable as additive in many areas (construction, food, oil
drilling, etc. etc.).
Synthetic Ox Gall:
I havn't the faintest idea. Just that the guy in the artists shop
told me he had a SYNTHETIC one when I asked for ox gall.
Here's a link to the one I bought:
